Just to note mmd_phy_indirect() isn't defined with inline specifier,
but just as static and it's used twice in the
drivers/net/phy/phy-core.c unit. So most likely the compiler won't
inline the function code in there. Anyway it's up to the PHY
library maintainers to decide. Please settle the issue with Heiner and
Andrew then. I am ok with both solutions and will do as you decide.
